Description
Technical field
The utility model belongs to technical field of concrete construction, and it is levelling to relate generally to road surface, stockyard, Wharf Surface and roofing
The concrete topping of Rotating fields, specifically a kind of Portland Cement Concrete Surface Course with reinforcing layer.
Background technology
Concrete topping is widely used on road surface, stockyard, Wharf Surface and the levelling Rotating fields of roofing, generally in surface layer
Configuration reinforcement mesh sheet is as casing play.Concrete tensile strength is extremely low, expands with heat and contract with cold, with the mechanics index of physics of reinforcing bar not
Match somebody with somebody, constraint is produced during deformation, so as to produce tension.When tension exceedes its tensile strength, concrete topping cracks, water
Invade along crack, chemically reacted after reaching rebar surface, the gradual corrosion of reinforcing bar, with the extension of time, corrosion aggravates.Iron
The volume of rust exceeds well over corrosion part reinforcing bar volume, is expanded in air-free concrete, produces huge stress accumulation, makes face
Layer surface structure（Protective layer）Crack and flake off rapidly, cause surface layer to destroy, influence the durability of main body.
Concrete above common fault is analyzed as follows in theory：
Reinforcing bar（Carbon steel）With the physical and mechanical parameter table of concrete
